4. A flexible car roof comprising root sheets arranged on the car side by side and extending from eaves to eaves thereof, said sheets having upstanding ribs along their opposite side margins, said sheets being normally adapted for approximate-contact with each other near the ridge portions of their side marginsonly, and side seam caps straddling the adjacent marginal ribs of said sheets and normally. adapted for approximate contact with the sides of said adjacent side marginal ribs at their ridge portions only whereby said sheets are adapted for independent oscillatory movement around a region near the ridge portion of either of their side margins.

5. A flexible car roof: comprising roof sheetsarranged on the car side by side and extending from eaves to eaves thereof, said sheets having upstanding ribs along their adjacent side margins that contact with each other at their middle portions only, and side seam caps secured to the car and straddling.

the adjacent marginal ribs of said sheets, said side seam caps being normally in contact with the sides of said adjacent side marginal ribs at the ridge only whereby said sheets are adapted for independent oscillatory movement around a region near the ridge margins.

3. car roof comprising a plurality of roof sheets extending from eaves to eaves of the car, said sheets having upstanding ribs along their adjacent side margins that portion. of either of their side contact with each other at the ridge only,

and seam caps secured to the car andspanning the adjacent side marginal flanges of said sheets, said seam caps contacting with the sides of the adjacent flanges of said sheets at the ridge only whereby said sheets are adapted for independent oscillatory movement around a region near the ridge portion of either or their side margins.

7. A car roof comprising a plurality of root sheets that extend "from eaves to eaves ot the car and have upstanding flanges along their side margins-said sheets tapering in width from ridge to eaves whereby the side marginal flanges ot" ad acent sheets are spaced further apart at the eaves than at the ridge, and seam caps secured to the car and spanning the side marginal flanges of adjacent sheets, said seam caps tapering in width from eaves to ridge where they contact with the side marginal flanges-of adjacent sheets and hold them substantially in contact with each. other whereby said sheets are adapted for independent oscillatory movement around a region near the ridge portion of either of their side margins.v 8. A car roof comprising a plurality of roof sheets that extend fromeaves to caves and have upstanding. flanges along their side margins, and seam'caps, secured to the car and straddlingthe side marginal flanges of adjacent sheets, the sidemarginal flanges of adjacent sheets'being in contact with each other only in the region of the ridge and the seam caps being incontact with the sides of said adjacent flanges only in the region of the ridge whereby said sheets are adapted for independent' oscillatory movement around a region near the ridge portion of either of their side margins.

9. A car roof comprising a plurality of roof'sheets that extend from eaves to caves of the car and are formed with side margi-' nal flanges of substantially inverted channelshaped section, and seam caps secured to the car and straddling the seam flanges of adajacent sheets, the side marginal flanges of said sheets being wider at the ridge than at the eaves and said seam caps being wider at the eaves than at the ridge whereby said sheets are adapted for independent oscillatory movement around a region near the ridge portion of either of their side margins.

10. A flexible car roof comprising a plurality of roof shcets arranged on. the car side by side, side seam covers secured to the car and spanning the side margins of adacent sheets, and means for securing an in ep'endent oscillatory movement of each roof sheet around a region near the middle of either of its side margins whenever there is movement of the sheet. j
